Improvement in spinning-wheels



UNITED STATES PATENT QEEIGE MURDOOK MCLEOD, OF ,GRAND HAVEN, MICHIGAN,ASSIGNOR TO ANDREW THOMSON, OF SAME PLAGE.

IMPROVEMENT INV SPINNING-WHEELS.

Specication forming part of Letters Patent No. 156,230, dated October27, 1'874; application led May 5, 1874.

To all whom t may concern:

Be it known that I, MURDocK MeLEoD, of Grand Haven, in the county ofOttawa and State of Michigan,'have invented an Improve,- Inent inSpinning-Wheels, of which the following is a speciiication:

The nature of this invention relates to an improvement in that class oi'spinning-wheels wherein the spindle isV driven by or through the agencyof a foot-treadle; and it consists in the peculiar devices for releasingthe spindle from the action of the driving-wheel, as more fullyhereinafter set forth.

Figure lis a perspective view of my irnproved spinning-machine. Fig. 2is an enlarged side elevation ot the head-stock, and the attachmentthereto, ot' the lever, which raises the spindle away from itsfriction-driv- In the drawing, A represents a table, supported bystandards B, between which is pivoted a foot-treadle, C, by means ofwhich a drivingwheel, E, is actuated through a pitnian, D. F F are twostandards bolted von the table, forminga head stock, between which isjournaled a driving-shaft, G, :carrying a pulley, H, rotated by anendless cord, I, passing around thedriving-pulley E and the said pulleyH. On the shaft G isa friction-wheel, K. L is the spindle, having aspooling-disk, a, and a friction pinion or pulley, M, adapted to run incontact with and be driven by the friction-wheel K. rlhe base or backend of the spindle runs in a step in the top of the standard F. The bodyof the spindlepasses through a slot, b, in the standard F, in which itmay be raised so as to remove the pulleyM from the wheel K, but isnormally kept in contact therewith by an elongated cap-bearing,

c, passing up through the top of the standard F, and pressed down by acurved spring, d,

attached at its base to one side of said stand ard. The shaft or spindleL is raised by a lever, N, pivoted to one side of the standard F with alifting-rod, O, pivoted to its rear end, and whose upper end bearsagainst the under side of the spindle. When the lever N is 4depressed bythe hand, the spindle is no longer driven by the foot-treadle, and isfree to turn in any direction, although the motion of the foot-'treadlemay be kept up. The lever N may be arranged to be depressed by the foot,if desired.

The spinning of the carded rolls is done at the end of the spindle inthe ordinary way, and when a length .of the yarn or thread is drawn, itis allowed to be wound upon the end of the spindle, when the spinnerreleases the spindle from the driving mechanism and unreels the yarnspun and wound upon the end, by pulling the yarn, after which thespindle is again allowed to be rotated, to wind the spun yarn upon thespindle near the spooling-disk a, when the spinning proceeds as before.

What I claim as my invention, and desire -the driving mechanism,substantially as described.
